Opis:
Kaempferide (3,5,7-trihydroxy-4'-methoxyflavone, 1), a naturally occurring flavonoid with potent anticancer activity in a number of human tumour cell lines, was first semisynthesized from naringin. Based on Mannich reaction of kaempferide with various secondary amines and formaldehyde, nine novel kaempferide Mannich base derivatives 2-10 were synthesized. The aminomethylation occurred preferentially in the position at C-6 and C-8 of the A-ring of kaempferide. All the synthetic compounds were tested for antiproliferative activity against three human cancer cell lines (Hela, HCC1954, SK-OV-3) by the standard MTT method. The results showed that compounds 1, 2 and 5-10 were more potent against Hela cells with IC50 values of 12.47-28.24 μM than the positive control cis-platin (IC50 41.25 μM), compounds 5, 6, 8 and 10 were more potent against HCC1954 cells with IC50 values of 8.82-14.97 μM than the positive control cis-platin (IC50 29.68 μM), and compounds 2, 3, 5, 6 and 10 were more potent against SK-OV-3 cells with IC50 values of 7.67-18.50 μM than the positive control cis-platin (IC50 21.27 μM).

Opis:
This work concentrated on the utility of hydrazonoyl halides in synthesis of bioactive heterocycles like triazoles, pyrazoles, pyrimidines and their fused derivatives which have a wide spectrum of pharmaceutical value. Herein we discussed the synthesis of new heterocyclic compounds containing fused pyrimidine rings derived from hydrazonoyl halides and their significant pharmaceutical importance as anticancer agents. New fused pyrimidine derivatives bearing 1,2,3-triazole moiety were prepared via reaction of enaminone 2 with and 6-amino-2-thioxo-pyrimidin-4-one and then with hydrazonoyl chlorides 6a-h. In addition 3-amino-6-(2-oxo-2H-chromen-3-yl)pyridine-2-carbonitrile (12) was submitted to react with carbon dioxide to afford 3-(1,2,3,4-tetrahydro-2,4-dithioxopyrido[2,3-d]pyrimidin-7-yl)-2H-chromen-2-one (15), which act as key molecule for synthesis of new series of fused prymidinethione derivatives containing coumarine moiety via its reaction with different selected derivatives of hydrazonoyl halides 6a-h. Structures of the newly synthesized compounds were confirmed using spectral data (IR, H1NMR and Mass spectrometry) and microanalytical methods. Also, they screened for their anticancer activity.

Opis:
Natural and synthetic lactones containing an aromatic ring exhibit a number of biological properties, e.g. antiproliferative, antifeedant or antimicrobial activity. This review deals with the synthesis and biological properties of lactones containing an aromatic substituent in the β-position of the lactone ring. The described group of compounds includes halolactones, hydroxylactones, unsaturated lactones and products of reductive dehalogenation of iodolactones. In addition to chemical transformations, biotechnological methods for obtaining optically active lactones have also been described, including the use of lipases in the chemoenzymatic pathway leading to the production of halolactones, kinetic separation of hydroxylactones in the process of enzymatic transesterification, microbial hydrolytic dehalogenation of iodolactones and enantioselective hydrolysis of the lactone ring. The biological activity of the obtained β-aryllactones was also briefly characterized.

Opis:
Introduction and objective. Since antiquity, C. babylonica (L.) L. extracts has been used as a remedy for primary health care in traditional medicine. In this study, a total of seven different crude extracts (acetone, chloroform, hexane, ethylacetate, methanol, ethanol and water) from branches and leaves of C. babylonica (L.) L. were prepared to determine antimicrobial and antiproliferative activity against cancer cell lines. Materials and method. MIC assay was used for antimicrobial activity against gram positive and gram negative bacteria, and one yeast. MTT assay was applied to screen the antiproliferative activity of seven extracts, and to determine dose- and time-dependent effects of the aceton extract on A549, PC-3, MCF-7, and HeLa cell lines. Results. The aceton extract of C.babylonica (L.) L. showed the best antibacterial activity against Bacillus cereus, P. aeruginosa and C. albicans (MIC: 1.6 mg/mL). GC-MS analyses allowed six compounds to be determined; the main constituents of acetone extract from C. babylonica (L.) L. were diacetone alcohol (53.47 %), 1-dexadecene (10.19 %) and 1-tetradecene (8.67 %). In addition, seven different solvent extracts at 500 μg/mL caused antiproliferative activity between 84% – 88%, compared to control. Dose-dependent effects of the extracts on A549 cells indicated that chloroform, ethyl acetate, and aceton extract were the most effective extracts with the IC50 values of 9, 33, and 36 μg/mL, respectively. Conclusions. The results clearly demonstrate that C. babylonica (L.) L. exhibited a strong antimicrobial effect and antiproliferative activity against cancer cells in vitro. Further studies are required to isolate and characterize the active pure compounds responsible for the antimicrobial and antiproliferative activities.
